IOS Security Research Engineer

Role Overview
We are seeking an iOS Security Research Engineer with strong knowledge of iOS internals and hands-on experience in reverse engineering, application security testing, and vulnerability research. This role focuses on identifying weaknesses in iOS applications and the platform, bypassing security controls, and researching advanced exploitation techniques.
Key Responsibilities
Perform reverse engineering of iOS applications (IPA) using static and dynamic techniques
Conduct iOS application penetration testing, including runtime hooking, method swizzling, and network traffic analysis
Analyze and bypass common iOS security mechanisms such as SSL pinning, jailbreak detection, anti-debugging, and code obfuscation
Research iOS internals including Objective-C/Swift runtime, Mach-O binaries, entitlements, code signing, and sandboxing
Perform malware analysis of iOS samples and suspicious applications (good to have)
Use, extend, and develop tooling for dynamic instrumentation and runtime analysis
Replicate and study publicly known iOS vulnerabilities and exploits
Participate in vulnerability research and exploitation, including logic flaws, sandbox escape concepts, exploit chaining, and basic memory corruption
Produce detailed security research reports and proof-of-concepts
